Description:
markdown
The presentation will start with some background on the requirements and relational databases. Next, we’ll build a basic ORM that allows creating simple tables and inserting, querying, and (if we have time) deleting records. Finally, the talk will cover some of the challenges of building a production-grade ORM, including caching, transactions, supporting multiple dialects, and we’ll briefly discuss security implications of ORMs, including SQL injection. Attendees will leave with a greater appreciation for the inner workings of the ORMs that are used on a daily basis, while understanding the challenges that go into building one. Applications rely on data, and relational databases are a convenient way to organize structured information. Object-relational mappers like SQLAlchemy and Django’s ORM are complex libraries, but they aren’t black magic. De-mystify some of the magic as we build the basics of an ORM in under an hour.
